Abstract: sFas (CD95) / FasL are hallmarks of apoptosis involvement in pathogenesis of HIV. We assess changes in soluble Fas /FasL, CD4 % and HIV-1 viral load in patients prior to the initiation of antiretroviral therapy (ART) and 6 months thereafter. A prospective longitudinal study on sixty consented HIV-1 positive adults. sFas and sFasL levels were measured by ELISA. CD4 cell counts and HIV-1 viralloads were measured using standard methods. Samples were analysed according to the manufacturers’ guidelines.There was a significant positive correlation between HIV-1 viral load and FasL at six months (M6) on treatment [r = +0.49, (0.03)]. There were no correlation between sFas/FasL and CD4 cell counts [ r = -33 (0.16), -31 (0.17) -23 (0.03) respectively]. The significant correlation between sFasL and HIV-1 viral load at six months of ART suggests that sFasL could be a signal biomarker for HIV-1 disease progression. We have shown in this study that high levels of sFasL depict high HIV-1 viral loads and advance state of the HIV disease. These biomarker should be investigated further in other settings.
